This tool removes every numeric digit from your text and leaves letters, spaces and punctuation as they are. It is more useful than it sounds. OCR output from scanned books is full of stray page numbers; code copied from a documentation site or a GitHub blob view arrives with line numbers glued to the front of each line; transcripts carry timestamps; and exported reports mix identifiers into the prose you actually wanted. Stripping digits in one pass is far faster than a manual regex, and because processing happens locally you can safely clean a document containing account numbers or personal details without uploading it anywhere.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
